BALL-BEARING;

Specification of Letters Patent.

Patented May 12, 1908..

Application filed May 16, 1906. Serial No. 317,129.

Ogontz, in the county of Montgomery and State of Pennsylwiuia, have invented certain Impro'vei'ucnts in Ball-Bearings, of which the following is a specification.

This invention is a ball-bearing adapted particularly for taking a thrust, as in the case ofholding a worm shaft, a propeller shaft or other constructions subjected to a longitudinal force, and its primary purpose is to provide a sim le,'inexpensive and efficient construction or such use.

In the accompanying drawings, Figure 1 represents a transverse sectional view of my improved bea'rinqdisposed between a shaft and a step therefor, and Fig. 2 represents a sectional plan view of the same.

The bearing comprises the pressed steel rings A and preferably conc'avo-convex, provided respectively with the annular races a and b between which are disposed-steel balls C. The rings are held together by the soft metal band D having the bottom flange d turned under the ring A to rovide a seat therefor and the to flange turned over the edge of thering to hold it in position with reference to the ring A and the balls C,

the ring B having the top convexity I) extending above the flange d. p

In the usual application of the improvemerits, a step E provided with the aperture e has the flanged resting thereon to support the ball-bearing, and a shaft F is provided with a bearing f resting on a'crown of the ring B and a boss of reduced extension f extending through the rings and band of the ball-bearing into the aperpure e of the step.

The periphery of the g Ais of larger Jiameter than the periphery of the ring B, and the opening through the ring A is of larger diameter than the opening through the ring B, so that the cylindrical projection of the F taottwith baring A, and so that the ring B can turn easily without'oon- I can be fitted snugly on the partf and turned freely without contact with the band I).

It will be understood that in this construction the thrust of the shaft F is carried by the ring B through the balls 0, the ring A and the flange d of the band l) to the ste E, the bottom ring being held stationary by friction, while the top ring is held frictionally to the shaft and revolves freely onthe balls Without wearing upon the band. By the foregoing construction arts are provided that can be pressed out, y means of dies, uniformly and at low cost, and assembled very readily. The rings are subjected to no wear exce ting from the balls and the soft metal jac 'et flanged over the edge of the revolving ring and turned under thee(lge of the stationary ring so as to receive the thrust confines the parts so that they cannot, possibly separate and forms a pillow which prevents breakagefrom sudden ars. Having described my invention I claim A ball bearing. comprising a pair of con cavo-convex rings having races therein, one of said rings having greater interior and exterior diameters than the other, balls in said races between said rings, a soft metal band having a diameter larger than the exterior diameter of said ring of smaller diameters and flanges which engage the convex surfaces of the respective rings, a bearing for sup orting said ring of larger diameters, and a s aft having a bearing resting upon the convex surface of said ring of smaller diam eters without making contact with the flange engaging said ring, said shaft having a reduced part 11 on which said ring of smaller diameters is xed. l

In testimony whereof I have hereunto set my name this 14th day of May, 1906, in the. presence of the subscribin witnesses.
